Abstract: In contemporary logistics operations, technology plays a pivotal role in replacing antiquated systems. This article proposes a comprehensive solution for securing goods in transit using a integration of cryptography and IoT technology to mitigate threats. In our proposed system cryptographic measures at logistics doors, requiring authorized personnel to give a hash function, specifically utilizing the MD5 encryption algorithm, to inspect the goods. It employs encryption technique to secure the passwords associated with access points along the transportation route. Upon door opening, an alert message is deliver to the sender via the Blynk App, enabling real-time tracking and location verification. Additionally, the system incorporates weight sensors to detect any tampering to the transported goods. Upon detecting such anomalies, the system triggers alarms or sends the alert to relevant stakeholders. The stakeholder can remotely access the system via the Blynk app to track the location. This integrated approach ensures the protection of goods throughout the journey, safeguarding against potential cyberattacks and theft incidents.
